The correct answer is:
If both assertion and reason are true but reason is not the correct explanation of assertion.
Critical temperature of a gas may be defined as that temperature above which it cannot be liqufied however high pressure may be applied on the gas.
Hence, $\mathrm{CO}_2$ cannot be liquified above its critical temperature.
According to Boyle's law
$P \propto \frac{1}{V}$ or $V \propto \frac{1}{P}$ (at constant $T$ and $\left.n\right)$
Hence, $\mathrm{CO}_2$ cannot be liquified above its critical temperature.
